. Application filed June 23, 1908. Serial No. 59,951.

To all whom it may concern:

Be it known that I, NlARTIN EVILLE, a citizen of the United States,residing at Chicago, county of Cook, and State of lllinois, haveinvented certain new and useful 1mprovements in Boller-B'earing Axles,of which the following is a specification,

My invention relates to improvements in roller-bearing axles of theclass suitable for use in carriages and wagons.

The object of my invention-1s to provide in a hub and axle,anti-friction and dust-- proof bearings that will be simple in structionand reliable in use.

With these objects in view my invention consists in a hub and axle and aplurality of COH- rolls interposed and adapted to reduce. the

proofing means which will be hereinafter clearly set forth.

The preferred form of my invention is illustrated in the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a side elevation of the axlearm and a. central longitudinalsection of the hub, and Fig. 2 is a perspective view of the roller cage.

Referring to the drawings, 1 indicates a hub, and 2 an axle-arm orspindle upon which the hub is journaled. The spokes '3 are securedbetween'the hub flanges 4 and are locked by means ofthe central flange 5and the widened portions 6 in the peripheral groove between the spokeflanges 4 as shown. Thus the construction of the hubis ideal as thereare no bolts or rivets to detract from its general appearance.- The hub1 is preferably a single casting of suitable metal. The inner bearingsurface 1 of the hub-is conical as is also the spindle 2, and these areof such contour that'if extended the surfaces would meet in a commonapex. The bore of the hub is shouldered as at l and 1 formingvertically-disposed annular bearing surfaces and =.the annular- .whichthe the spindle is provided and the flanges or extensions 15 and 16which project beyond the bearing-sin both directions.

Tnterposed between the spindle 2 and the bearing surface 1 of thehubis'a roller bearing cage formed of the end members 11l1- andtheconnecting rods 14, and in anti'friction rollers 13 are mounted. Therollers'13 are conical and their outer surfaces if produced wouldconverge in a common apex with the spindle 2 and the surface 1 of thehub, thus forming a perfect rolling contact between the parts. The endsof the rollers 13 are reduced, forming journals 13 which are mounted inradially disposed slots in the end members 11 of the cage. The members11 are annular metal members which fit snugly upon thespindle and theslots 12 extend onlypart way through said members leaving the outerfaces unbroken, which in a large meas ure prevents dust and grit fromaccumulating in the bearings. The usual collar? is provided between thespindle 2 and the axle proper which fits within the flange l5 and athrust washer 8 of suitable hard metal is provided between the collar 7and the inner cage member 11. A packing and dustproofing washer 9preferably of rubber is securely seated against the inner shoulder l ofthe hub 1 as shown and securely closes the space between said shoulder,the washer 8 and the periphery of the adjacent member 11. .The usualretaining nut 10. screwed to cage is held between said nut and thewasher 8. "The connecting-rods 14 are adapted to secure the enlargedcylindrical portions defined by.

thefianges' 15 and 16 and bear against-the shoulders l and 1respectively.

Having described my invention what I claim as new anddesire to secure byLetters Patent, is: I

In a device of the class. described, an axle spindlehaving a collar atone end and a nut threaded upon the other end in combination with a hubhaving a bore of greater diameter than that of the spindle, a rollerbearing cage mounted on said-spindle. rollers in said cage forming abearing between the'spindle and said hub, said hub being provided withinternal' outwardly faced 'roc In testimony-whereof I have signed myname to this specification 1n the presence-0f 10 tW subscribingWll'IlGSSBS.

shoulders near each end, one of said shoulders bearing against said nut,a metallic aslier and soil packing interposed between said collar andthe opposite shoulder, said soft packing surrounding the inner end ofsaid cage and said washer and said nut bear ing against the respectiveends of said cage, substantially as described.
